Patent CA-2316891-A1 (CA)
Title: Time lag approach for measuring thermal conductivity and specific heat
Inventor: BONNE ULRICH
IPC: G01N25/18
Filed: 1998-12-10
Abstract: A method and apparatus for providing a more direct approach to determine the thermal conductivity, thermal diffusivity and specific heat of a fluid of interest, independently of the amplitude of the sensor output. This is preferably accomplished by measuring one or more variable phase or time lags between selected input and output AC signals, and directly deriving the thermal conductivity, thermal diffusivity and specific heat therefrom. Such derivation is therefore less dependent than amplitude-based sensors on occasional or unpredictable drift in sensor resistive elements.

To cash a check or conduct another form of business transaction, whether at an attended customer service station or at an automated machine, the encoded data on the identification card is read and the customer is required to input the personalized identification number assigned to the card. The transaction is not approved unless the customer correctly inputs the assigned identification number. In contemplated embodiments, the encoded data along with data regarding the transaction requested by the customer, e.g., obtained by optical scanning of a check or other item presented by the customer, is transmitted to a central computer system for execution of an approval-disapproval analysis or algorithm.
Patent CA-2325248-A1 (CA)
Inventor: KINNEY DENNIS
IPC: G01N31/22
Filed: 2000-11-07
Abstract: A method of determining the effectiveness of a sterilization cycle in a sterilization chamber by the use of an indicator containing DNA and a dye which can be bound thereto. The indicator containing DNA is placed in the sterilization chamber prior to the beginning of the sterilization cycle. When the DNA is subjected to heat and steam, the molecule is fragmented so that it is no longer capable of binding the dye. The DNA is withdrawn from the indicator after the sterilization cycle, contacted by a solution of the dye and, thereafter, dipped into wash water. If sufficient fragmentation has taken place, a substantial percentage of the dye will be washed off during the second dip. This is easily recognized by the operator and the efficacy of the cycle can be determined. On the other hand, if insufficient heat and steam has been applied, the remaining DNA will retain the dye and little or no change in color will be observed. In such a case, the operator will immediately recognize that the sterilization cycle was ineffective.

Patent CA-2326580-A1 (CA)
Inventor: MULLINS PATRICK T
IPC: E02F3/85
Filed: 2000-11-23
Abstract: The position of the blade of a motor grader is controlled to maintain a smoothly graded surface even when the grader's front wheels travel over undulating ungraded ground. This is accomplished by sensing the degree to which the grader frame pivots with respect to the rear wheels and employing the pivot angle to derive the resultant change in blade position. That change is used to operate a mechanism that produces movement of the blade relative to the earth thereby compensating for effects of the pivoting action.

IPC: H04W24/02
Filed: 2000-12-19
Abstract: Logical coverage areas are dynamically rearranged to meet the traffic needs of a wireless switching system. Further, the logical coverage areas do not have to be initially provisioned during deployment of the wireless switching system since the initial determination of the logical coverage areas is automatically performed. Once the logical coverage areas are established, the logical coverage areas adapt to the changing needs of the community of wireless handsets. A first embodiment allows the base stations to control the rearrangements, and a second embodiment allows a system wireless controller controlling the wireless switching system to control the rearrangements.

Abstract: An optical transmission system is formed to include an optical phase conjugator at alternate repeater sites to minimize the presence of four-wave mixing and other Kerr effect nonlinearities in systems using optical fiber transmission paths (particularly in systems using DWDM and launching relatively high power signals into the low dispersion fiber). Raman gain is included in each fiber span (or in alternate fiber spans) so as to provide a "negative absorption" along the length of the fiber and thereby provide for essentially symmetrical power distribution along the length of each span, where the presence of such a symmetric power distribution on each side of an optical phase conjugator has been found to significantly improve its performance.

Title: Method for manufacturing a multi-layered moulded synthetic part and thus obtained part
Inventor: HACKWELL ROGER
IPC: B29K69/00
Filed: 1999-10-15
Abstract: The invention relates to a method for manufacturing a multi-layered moulded synthetic part comprising a preformed elastomeric moulded skin (5), a moulded carrier (8) of a thermoplastic material and optionally an intermediate foam layer (6). In this method, the elastomeric skin (5) is moulded in a first step and the thermoplastic material for the carrier (8) is subsequently moulded in molten state to the back of said moulded skin (5). According to the invention, the moulded skin is made of a thermosetting synthetic material.  Compared to a thermoplastic skin, such a thermosetting skin is less subjected to visible defects, in particular in case it has been provided with a superficial texture such as a leather grain, when the thermoplastic carrier is moulded thereto. Moulding of the thermoplastic carrier can be done by an injection moulding, an injection pressure moulding or a low pressure moulding technique.
